So my frogspawn has been doing really well up in till I add a peppermint shrimp the other day and cam home from work and found this and rapidly check my water levels and everything was pretty much sopt on but my nitrate was at 10ppm so not really that hight to do something like this in the picture posted below p.s got rid of the peppermint shrimp just in case and will it grow back and or die completely
